What is the simplest SOAP example using Javascript?
To be as useful as possible, the answer should:
Easily consume SOAP Web services with JavaScript -> Listing B
function fncAddTwoIntegers(a, b)
{
varoXmlHttp = new XMLHttpRequest();
oXmlHttp.open("POST",
"http://localhost/Develop.NET/Home.Develop.WebServices/SimpleService.asmx'",
false);
oXmlHttp.setRequestHeader("Content-Type", "text/xml");
oXmlHttp.setRequestHeader("SOAPAction", "http://tempuri.org/AddTwoIntegers");
oXmlHttp.send(" \
<soap:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' \
xmlns:xsd='http://www.w3.org/2001/XMLSchema' \
xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'> \
<soap:Body> \
<AddTwoIntegers xmlns='http://tempuri.org/'> \
<IntegerOne>" + a + "</IntegerOne> \
<IntegerTwo>" + b + "</IntegerTwo> \
</AddTwoIntegers> \
</soap:Body> \
</soap:Envelope> \
");
return oXmlHttp.responseXML.selectSingleNode("//AddTwoIntegersResult").text;
}
This may not meet all your requirements but it is a start at actually answering your question. (I switched XMLHttpRequest() for ActiveXObject("MSXML2.XMLHTTP")).
This is the simplest JavaScript SOAP Client I can create.

Some great examples (and a ready-made JavaScript SOAP client!) here: http://plugins.jquery.com/soap/
Check the readme, and beware the same-origin browser restriction.
function SoapQuery(){
var namespace = "http://tempuri.org/";
var site = "http://server.com/Service.asmx";
var xmlhttp = new ActiveXObject("Msxml2.ServerXMLHTTP.6.0");
xmlhttp.setOption(2, 13056 ); /* if use standard proxy */
var args,fname = arguments.callee.caller.toString().match(/ ([^\(]+)/)[1]; /*Имя вызвавшей ф-ции*/
try { args = arguments.callee.caller.arguments.callee.toString().match(/\(([^\)]+)/)[1].split(",");
} catch (e) { args = Array();};

// Send the POST request
xmlhttp.setRequestHeader("MessageType","CALL");

//WScript.Echo("Запрос XML:" + q);
xmlhttp.send(q);

The question is 'What is the simplest SOAP example using Javascript?'
This answer is of an example in the Node.js environment, rather than a browser. (Let's name the script soap-node.js) And we will use the public SOAP web service from Europe PMC as an example to get the reference list of an article.
const XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;
const DOMParser = require('xmldom').DOMParser;
function parseXml(text) {
let parser = new DOMParser();
let xmlDoc = parser.parseFromString(text, "text/xml");
Array.from(xmlDoc.getElementsByTagName("reference")).forEach(function (item) {
console.log('Title: ', item.childNodes[3].childNodes[0].nodeValue);
});
}
function soapRequest(url, payload) {
let xmlhttp = new XMLHttpRequest();
xmlhttp.open('POST', url, true);
// build SOAP request
xmlhttp.onreadystatechange = function () {
if (xmlhttp.readyState == 4) {
if (xmlhttp.status == 200) {
parseXml(xmlhttp.responseText);
}
}
}
// Send the POST request
xmlhttp.setRequestHeader('Content-Type', 'text/xml');
xmlhttp.send(payload);
}
soapRequest('https://www.ebi.ac.uk/europepmc/webservices/soap',
`<?xml version="1.0" encoding="UTF-8"?>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
<S:Header />
<S:Body>
<ns4:getReferences xmlns:ns4="http://webservice.cdb.ebi.ac.uk/"
xmlns:ns2="http://www.scholix.org"
xmlns:ns3="https://www.europepmc.org/data">
<id>C7886</id>
<source>CTX</source>
<offSet>0</offSet>
<pageSize>25</pageSize>
<email>ukpmc-phase3-wp2b---do-not-reply@europepmc.org</email>
</ns4:getReferences>
</S:Body>
</S:Envelope>`);
Before running the code, you need to install two packages:
npm install xmlhttprequest
npm install xmldom
Now you can run the code:
node soap-node.js
And you'll see the output as below:
